Sale price
A discount is just a slice taken off the list price. Enter the original price and the percent off, and this calculator shows the sale price and the dollars you keep in your pocket. Drag the slider to compare a 20%-off tag against a 50%-off one in an instant.
To find the saving, multiply the price by the discount and divide by one hundred. A 25% discount on an $80 item saves $20, so the sale price is $60. The bigger the percent, the more comes off — but the saving is always measured against the original price, not the sale price.
Two coupons rarely add up the way they look. A 30%-off deal followed by a 20%-off code is not 50% off — the second cut applies to the already-reduced price, so the real saving is 44%. When discounts stack, apply them one after another rather than summing the percents.
The sale price shown here is before tax. Sales tax is added on top of the discounted figure at checkout, so the amount you actually hand over is usually a little higher. Use this tool to know the shelf price; add your local tax rate for the till total.
How do I find the original price from a sale price?
Divide the sale price by one minus the discount as a decimal. A $60 item at 25% off came from $60 / 0.75, which is $80.
What percent off is a buy-one-get-one-free deal?
Across the two items it works out to 25% off, not 50%. You pay full price for one and nothing for the other, so the pair costs three quarters of two full prices.
Is a 50% off coupon the same as half price?
Yes. Fifty percent off removes half the listed price, so a $40 jacket becomes $20. Any percent off is simply that fraction of the price taken away.
Does the discount apply before or after tax?
Almost always before. Stores discount the shelf price first, then add sales tax to the lower amount, so the percent off never touches the tax line.
